1 Claim. 'l
This invention has for :its object to provide an improved dispensing valves "for squeeze .tube containers.
This invention relates to a squeeze tube container used for dispensing liquids such as shaving cream, tooth paste, and :the like, comprising a body of compressible material merging with a cap having an egress opening in its top wall, and means cooperating with the cap to release and cut off the flow of liquid from the tube container after use.
For the purpose of aiding in the explanation of the invention I show in the accompanying drawing and hereinafter describe one practical embodiment of it. It is to be understood, however, that this embodiment is presented merely by way of illustration and that specific showing and description of it are not to be construed in any fashion as limiting the appended claim short of the true and comprehensive scope of the invention in the art. There are, of course, numerous methods of performing the mechanical features of my invention of'which I have shown but one.
In the said drawing- Figure l is a fragmentary vertical sectional view of the squeeze tube container cap in its open position.
Figure 2 is a fragmentary vertical sectional view of the squeeze tube container cap in its closed position.
Figure 3 is a plan view of the pedestal foundation member shown in Figures 1 and 2, the other elements of the device being omitted.
Figure 4 is a plan view of the squeeze tube container.
Like numerals of reference indicate corresponding parts in the various figures.
The reference numeral I designates a squeeze tube container in the form of a compressible tube, 2 designates the cap thereof which is provided with an egress opening 3 forming the discharge mouth in the top wall of the cap. In the top wall there is also provided a bore 4 for the rece tion of the dowel or pin integral with the pedestal, and a bore 5 through which the integral upstanding portion of the non-rotatable axially movable valve member extends.
The non-rotatable axially movable valve member B is provided at its upper end with a wall 1 of ample thickness having formed therein an opening 8 having three vertical walls and an inclined wall 9 having a perpendicular portion I 0. On the top surface of the aforementioned valve member there is provided an integral upstanding portion II that extends through and slidably fits 2 in the bore provided .thereforin the top twalli'of the cap.
Adjacent the lower edge of the non-rotatable axially movable valve member there may be provided a fluid tight packing I2.
The pedestal member 13 is fixedly mounted in the pedestal foundation member as at 14, and comprises a stem terminating in an enlarged head l5 provided with complementary formed vertical planes that frictionally engage the vertical planes provided in the valve, whereby the valve is guided on the head I5 on being forced up to open position, and on being forced down to closed position.
The dowel or pin I6 integral with the enlarged head is provided to prevent the deflection of the pedestal when the tube is squeezed in the dispensing operation, and also in the closing operation.
It is obvious that when the valve is forced down in closed position as shown in Figure 2, the inclined surface of the enlarged head. of the pedestal and the inclined plane provided in the valve are in sealing contact.
The pedestal foundation member is provided with an integral upstanding skirt I1, and a transverse member l8 leaving through openings l9 and 20 therein through which the content of the tube such as shaving cream is forced in the squeezing operation to reach the under surface 2| of the wall of the valve to force it upward to open it in the dispensing operation. The lower end of the valve member is circumscribed and guided by the skirt on the foundation member.
On the transverse member in the pedestal foundation member there is provided a leaf spring 22 adapted to lock the valve in closed position as shown in Figure 2. On the inner wall of the valve there is provided a protuberance 23 that cooperates with the leaf spring to hold the valve in locked position.
Operation When an amount of the content such as shaving cream is desired, the tube is manually squeezed imparting pressure to the shaving cream, which in turn is transmitted to the inner wall 2| of the valve 6 which forces it up in the cap leaving an opening through which the cream is forced up to and through the egress for use. When the required quantity has been obtained, the valve member 6 is manually forced down by applying force on the top of the member II which projects through the upper wall of the cap, When the valve is down in closed position the resilient leaf spring 22 slips over the protuberance 23 and in a certain physical embodiment, it is to be un- V derstood that modifications of the structure may be made by those skilled in this art without departing from the invention as expressed in th claim which follows. r
I claim:
A squeeze tube container, comprising, in combination a tube body of compressible material, a
cap connected to the tube body having an egress in the top wall of the cap, and also having therein a bore to receive a dowel, and a through bore;
a non-rotatable axially slidable valve member having a top wall having therein a through opening circumscribed by Vertical sides and an inclined side, and also having an upstanding member adapted to pass through the through opening provided therefor in the top wall of the cap, a pedestal foundation member having a transverse member therein and an upstanding skirt therearound, a leaf spring of L shaped configuration mounted on and connected to the transverse member, the non-rotatable axially slidable valve I spring to lock thevalve 4 member being mounted in and having its lower end portion circumscribed by the upstanding skirt of the pedestal foundation member, a fluid tight seal member in the non-rotatable axially movable valve member and circumscribed by the upstanding skirt on the pedestal foundation member, a pedestal member mounted on and connected to the transverse member and terminating in an enlarged head portion and provided with complementary Walls which cooperate with the walls in the through opening in the top wall of the non-rotatable axially movable valve member, and also being provided with a dowel to engage in the bore provided therefor in the top wall of the cap, and a protuberance on the inner wall of the valve adapted to cooperate with the leaf when manually closed.
